Strength and chloride permeability of self consolidating concrete using waste materials

The utilization of industrial waste materials in construction industries has become an important factor in sustainable development. The selection of correct industrial waste materials specific to design requirement and usage will ensure the success rate of the materials to be used in construction industries. To identify the suitability of the waste materials as construction materials, a study on the properties, performance and durability of the materials in design medium are essential. This research will focus on the strength characteristic and the chloride permeability level of Self Consolidating Concrete (SCC) containing Recycled Concrete Aggregate (RCA) and Waste Paper Sludge Ash (WPSA). The influence of RCA content in the range from 0% to 100% of natural aggregate to the strength characteristic and the chloride permeability level of SCC containing optimum levels of WPSA mixes was identified and comparedwith SCC containing normal mixes. The SCC test specimens cured under water at tested for the compressive strength at age 3-day, 7-day, 14-day, 21-day, 28-day, 56-day and 90-day and chloride permeability were determined at age 28-day, 56-day and 90-day. The result indicated that the compressive strength and chloride permeability of SCC containing 100% RCA replacement show comparable performance with normal mixes of SCC
